DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMULANTS/19/
 ">Motivic and topological zeta functions of matroids</a>\nby Max Kutler (T
 he Ohio State University) as part of Queen Mary University of London Algeb
 ra and Number Theory Seminar\n\n\nAbstract\nWe associate to any matroid a 
 motivic zeta function. If the matroid is representable by a complex hyperp
 lane arrangement\, then this coincides with the motivic Igusa zeta functio
 n of the arrangement. Although the motivic zeta function is a valuative in
 variant which is finer than the characteristic polynomial\, it is not obvi
 ous how one should extract meaningful combinatorial data from the motivic 
 zeta function. One strategy is to specialize to the topological zeta funct
 ion. I will survey what is known about these functions and\, time-permitti
 ng\, discuss some open questions.\n
